Vestibular CCK signaling drives motion sickness-like behavior in mice.

Travel can induce motion sickness (MS) in susceptible individuals. MS is an evolutionary conserved mechanism caused by mismatches between motion-related sensory information and past visual and motion memory, triggering a malaise accompanied by hypolocomotion, hypothermia, hypophagia, and nausea. Vestibular nuclei (VN) are critical for the processing of movement input from the inner ear.

Lung ultrasound findings in pediatric patients with COVID-19.

During the pandemic caused by the novel coronavirus (COVID-19), lung ultrasound has been used to diagnose and monitor respiratory condition. The aim of the study was to describe lung ultrasound findings in children with a COVID-19 infection. Patients younger than 18 years old and positive for COVID-19, admitted to pediatric tertiary referral hospital were included.

Neonates With Urinary Tract Infection: Is a Lumbar Puncture Always Indicated?

Background: Our objectives were to determine the prevalence of and to identify risk factors for coexisting bacterial meningitis (BM) in neonates with urinary tract infection (UTI).

Methods: A cross-sectional study was conducted at pediatric emergency department of a tertiary teaching hospital from 2001 to 2017. Infants <29 days of age with UTI (≥10,000 colony-forming units/mL of a single pathogen from a catheterized specimen in association with positive urinalysis) were included.

Lung Ultrasound to Assess the Etiology of Persistent Pulmonary Hypertension of the Newborn (LUPPHYN Study): A Pilot Study.

Introduction: Persistent pulmonary hypertension of the newborn (PPHN) is a neonatal syndrome associated with significant morbidity and mortality that is caused by the failure of postnatal drop in pulmonary vascular resistance. In extreme cases, patients may require extracorporeal membrane oxygenation therapy (ECMO). The aim of this study was to explore lung ultrasound (LUS) patterns in newborns with PPHN requiring ECMO.
